Unformatted text preview: period using graphs. Suppose we are in an equilibrium as described and illustrated in part ( iv ) : In time period 1, labour market equilibrium is ( w ± 1 ;N ± 1 ) , and the goods market equilibrium is ( r ± 1 ;Y ± 1 ) : Let us now introduce a government, who neither spends, nor taxes. However, it likes to enact laws. Let us suppose that the government decides to impose a minimum wage w m 1 at the start of time period 1. ( v ) If the minimum wage w m 1 < w ± 1 , derive the new output supply curve b Y s 1 by varying period 1±s interest rate, as we did in the lecture. How would the equilibrium in the labour and goods markets change? ( vi ) If the minimum wage w m 1 > w ± 1 , derive the new output supply curve b Y s 1 by varying period 1±s interest rate, as we did in the lecture. How would the equilibrium in the labour and goods markets change? 1...
